WINDMILL.

SPECIFICATION forming part of Letters Patent No. 737,788, datedSeptember 1, .1903.

Application filed January 19, 1903. Serial No. 139,677. (No model.l

To all wwnt it may concern:

Be it known that I, HARBERT B. SMITH, a citizen of the United States,residing at Langley, in the county of Ellsworth and State of Kansas,have invented certain new and useful Improvements in Wind mills; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention is an improved windmill; and it consists in the peculiarconstruction and combination of devices hereinafter fully described andclaimed.

The object of my invention is to effect improvements in the constructionof a windmill whereby the pump-rod is prevented from stopping on adead-centeI-,whereby the pumprod is cushioned to prevent the stocksthereof from jerking and jarring the pump when the pump-valve primes orcatches, and to effect improvements in the construction of the framewhich carries the wind-wheel.

In the accompanying drawings, Figure l is a side elevation of a windmillembodying my improvements, partly in section. Fig. 2 is a similar viewat right angles te Fig. 1, and Fig. 3 is a top plan view of the same.

The cap-plate 1, which forms Vthe upper side of the tower 2 and tothecorners of which the upper ends of the corner-studs 3 are bolted, isprovided at its center with an opening through which extends a dependingbracetube 4, the upper end of which is connected by a screw-coupling 5and extends through said turn-table. On the under side of the cap-plate1 is an annular boss 6, which surrounds the base-tube 4, and on thelatter is clamped a collar 7 by means of a set-screw 8, said cellarbearing against the under side of the boss. On the upper side of thecap-plate 1 and disposed concentrically with reference to the brace-tube4 is a ball-race 9. The turntable 5 has a corresponding ball-race 10 onits under side, and bearing-balls 11 operate in the said ball-races. Bythis construction and combination of devices friction between theturn-table and the cap-plate is minimized, as will be understood.

The lower end of the brace-tube 4 is braced by means of a collar 12,which is engaged therewith, and stay-rods 13, which extend radially fromthe collar to the corner-'studs 3 of the tower. Stay-rods 14 arehereshown, which connect said corner-studs to the corner portions of thecap-plate.

A pair of standards 15, which are in practice gas or water pipes ofsuitable length and diameter, have their lower ends screw-threaded andengage with screw-threaded openings in the turn-table. To the upper endsof the said standards are connected bearings 16 by means of similarscrew-couplings, and to the said standards near their lower ends aresecured bearings 17 by means of bolts 18.

The shaft 19 of thewind-wheel 20 is journaled iu the bearings 16 and isprovided at its ends with crank-disks 21, the wrists 22 of which aredisposed in planes ninety degrees from each other. A counter-shaft 23isjournaled in the bearings 17, is provided with similar crank-disks 28atl its ends, and at a point intermediate its ends is provided with acrank 29. Pitmen 30 connect the wrists of the crank-wheels 2l 28, and itwill be understood that when the Wind-Wheel is revolved rotary motion iscommunicated to the countershaft 27.

A standard 3l, which is in practice a pipe of suitable length anddiameter, has its lower end screwed in an opening in one side 0f theturn-table, and to the upper end of the said standard is connected anoutwardly-extending horizontal arm 32, which is also a similar pipe, byan elbow 33. An upwardly and inwardly extending substantially invertedU- shaped arm 34, which is also preferably a pipe, has its lower outerportion connected to the outer end of the arm 32 by an elbow 35, and thevertical outer portion of the said arm 34 is provided with adiametrically enlarged sleeve 36, fixed thereto, and to which the forkedor. bifurcated outer end of the walking-beam 36 is pivotally connected,as by a bolt 37, the said bolt serving also to connect said sleeve tothe said arm 34. The said walking-beam is provided near its free end,which is disposed directly above the center of the turn-table andcap-plate, with an annular enlargement 38, through the bore of whichextends the upper end of the pumprod 39. In the sides of said annularenlargement and transversely disposed with reference to thc saidwalking-beam are slots 40,

which are engaged by a pin 4l, that extends through and projects fromopposite sides of the pump-rod. Hence the latter is pivotally connectedto the walking-beam and is adapted to move independently thereof to anextent equal to the length of the slots minus the thickness of the pin4 1. A coiled retractile spring 42 connects the inner end of the arm 34to the walking-beam at a suitable distance from the free end of thelatter and draws upwardly on the walking-beam. On the upper portion ofthe pump-rod above the Walking-beam and bearing thereon is a coiledextensile spring 43, the upper end of which is connected to the pump-rodby any suitable means-as by a nut or pin, and the function of the saidspring 43 is to normally elevate the pump-rod with reference to thewalkingbeam lo dispose the pin 4l normally in the lower ends of theslots 40. A pitman 44 connects the free end of the walking-beam 36 tothe crank 29 of the counter-shaft 27.

From the foregoing it will be understood that when the wind-wheel is inoperation reciprocating motion will be communicated to the pump-rod andthat by means of the walking-beam and the springs 42 43 the pump-rod iscushioned, so that the stocks thereof are prevented from jarring androcking the pump when the valve-primes or catches.

The turn-tableis provided with an upstanding pivot 45for the inner endofthe vane 46, which may be either of the construction here shown or ofany other suitable construction, and is in practice provided with meansfor turning it on its pivot to throw the windwheel into or out ofoperation. The means for operating the vane constitute no part of mypresent improvements, and hence are not shown and described herein, asthey are well known to those skilled in the art to which my inventionrelates.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, operation, and advantages of myinvention will be readily apparent, it is thought, without requiringamore extended explanation.

Various changes in the form, proportion,

vand the minor details of construction may be resorted to witho utdeparting Jfrom the principle or sacrificing any of the advantages ofthe invention.

Having thus fully described my invention, what I claim as new, anddesire to protect by Letters Patent, is

1. In awindmill, the combination of a windwheel having a shaft providedwith cranks, the wrists of which are out of line with each other, acounter-shaft having similar cranks and provided also with a crank 29,pitmen connecting the wrists of the cranks of the wind-wheel andcounter-shaft, a walkingbeam, a pitman connecting the latter to thecrank 29, and a reciprocating rod connected to the walking-beam,substantially as described.

2. In combination with a walking-beam, a Wind wheel and connectionsbetween the wind-wheel and walking-beam to operate the latter, a springbearing upwardly on the walking-beam, a reciprocating rod having pivotaland slidable connection with the walkingbeam, and a spring coacting withsaid Walking-beam and rod to normally depress the latter with referenceto the walking-beam, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit- HARBERT B. SMITH.
